Thanks for the heads-up but that's not a crash - it's actually an ICE warning (you can tell because it says "ICE03" in front). When WiX crashes, it will display a stack trace so that we can diagnose and fix the problem.
The problem you've encountered is that MSI identifiers are supposed to be 72 characters long or less. When the modularization guid and added (this only happens in merge modules), it's much easier to go over this limit because you're effectively limited to ~36 characters (I forget exactly how many). Basically you can only use half of the 72 which are available. This brings up a common question - why is the limit 72 characters? The answer is that at the time MSI was first created, it was very important to keep the size of strings in the MSI down to a minimum since installations were being packed onto floppy disks. Nowadays, the limitation seems unnecessary but there are still two good reasons to follow them: 1. Keeping identifiers under 72 characters long ensures that they are relatively succinct. 2. If you ship a merge module to another group that does follow the 72-character limit and your merge module does not, you will break validation for them (which is not very nice). In practice, the Visual Studio group does this all the time and they've gotten a ton of negative feedback about the practice. So please be a good citizen when creating merge modules.

Everything has been going well until one directory which has files with long file names gets processed by light. light.exe crashes because of this. The component tmp.wxs(3482) : warning LGHT1076 : ICE03: String overflow (greater than length permitted in column); Table: Component, Column: Component, Key(s): apifnsm_adjust_agc_module_params.html.E2904247_E12E_4BA8_9815_E506E96D53DA The component value is 74 characters long. I believe from reading on the platformsdk.msi usenet group that 72 is the limit. I can probably get my script to adjust the strings to avoid the problem, but you might like to know about the crash. Apart from that heat looks like a useful and powerful tool. Thanks. Neil ------------------------------------------------------------------------- Using Tomcat but need to do more?
